CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 556,766, dated March 24, 1896.

Application filed July 22, 1895. Serial No. 556,752. (No model.)

To coZ wwm t may concern.-

Be it known that we, CHARLES J. NUTT, residing at Otley, in the county of Marion, and FRANCIS BUTIN, residing at Galesburg, in the county of Jasper, State of Iowa, citizens of the United States, have invented a new and useful Car-Coupling, of which the following is a speeiiication.

The invention relates to improvements in car-couplings.

The object of the present invention is to provide a simple and inexpensive car-coupling which will be capable of effecting the operation of coupling automatically, and which may be readily uncoupled from the tops and sides of cars without going between them,

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view of a earconpling constructed in accordance with this invention and shown applied to a car. Fig. 2 is a longitudinal sectional view, the coupling-pin being set for automatic coupling. Fig. 3 is a horizontal sectional view of two draw-heads coupled. Fig. i is a detail view of the slidin g pin supporting block.

Like numerals of reference indicate corresponding parts in all the figures of the drawe ings.

l designates a draw-head having a link opening or cavity and mounted on a ear 2. The draw-bar or rear portion of the draw-head is laterally offset, and is provided with a forwardly-projecting rigid arm 3, and the latter is provided with a coupling-pin perforation i, and is adapted to enter the mouth of a corresponding draw-head and to be engaged by the coupling-pin 5 thereof, whereby the two draw-heads are coupled. f he rigid horizontallyedisposed arm 3 is arranged parallel with the draw-head proper, l, and is located at one side` thereof, and only one pin 5 is necessary for coupling the two draw-heads- Each drawhead is provided at one side, opposite to the rigid horizontal arm 3, with a vertical pocket i5, which is adapted to receive the couplingpin that is not in actual use when the two draw-heads are coupled.

Within the draw-head lis mounted a sliding block 7, which is adapted to be moved forward to a point beneath the upper portion of the couplingpin perforation S of the draw head to support the coupling-pin in an elevated position preparatoryto automa-tic eoup ling'. NV hen the coupling-pin is supported in an elevated position, as illustrated in Fig. of the accompanying drawings, it is adapted to be engaged by the rigid horizontal arm 3 of another draw-head and to be moved rearward from beneath the coupling-pin to cause the latter to fall and engage the horizontal arm entering the mouth of the draw-head.

The sliding pin -supporting block is provided at one side with a horizontal arm 9, arranged in a slot lO of the adjacent side of the draw -head and projecting therefrom, and adapted to be engaged by a depending arm ll of a transverse rock-shaft l2. The rockshaft l2 is journaled on the car in suitable bearings thereof, and is disposed transversely of the same, and it is provided at its ends with crank-handles 1S. lt is provided with a centrally-arranged horizontally-disposed arm li, and the latter extends longitudinally of the car-coupling and is connected by a chain with the coupling-pin. lVhen the arm ll is swung forward the arm li swings upward and lifts the coupling pin sufciently to effect the operation of uncoupling before the arm ll reaches the horizontal arm 9 of the sliding block, and the continued forward movement of the arm ll carries the slidin block forward to a point beneath the coupling-pin, which is maintained in an elevated position during this operation by the arm l-i of the rock-shaft. As soon as the rock-shaft is released the pin drops and is supported by the sliding block 7 and is maintained by the same in position for automatic coupling.

The operation of uneoupling is effected from the top of a car by a bell-crank. lever l5, which is fulorumed at its angle, and has one of its arms extending upward and forming a handle, and its other arm extending outward and connected with the arm li of the rocleshaft l2 by a chain 1G. By swinging the bell-crank IOL) lever on its pivot the arm ll is moved upward and the coupling-pin is elevated. This operation also swings the arm 1l forward and sets the coupling pin preparatory to automatic coupling.

It will he seen that the cancoupling is exceedingly simple and inexpensive in construcy tion7 that it possesses great strength and durability, and that it is positive and reliable in its operation.

It will also be apparent that the car-coupling is capable of automatic coupling and may be readily uncoupled Without going between cars.

Changes in the ii'orin7 proportion, and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention.

vVhat We claim is" l. ln a car-coupling, a draw-bar provided at one side with a draWhead rwith an opening or cavity, and having at the opposite side a horizontal arm arranged parallel with the draw-head and having its front end arranged substantially in the saine plane as the front of the draw-head, said arm being provided with a coupling-pin perforation and adapted to enter the opening or cavity of a corresponding drawdiead, substantially as described.

9. In a car-coupling, the combination of a draw-hoad provided at one side with a horizontal slot, a sliding pin-supporting block mounted in the draw-head, and having a horizontal arm projecting through the slot thereof, a coupling-pin, and a rock-shaft having an arm connected with the coupling-pin and adapted to raise the same, said rock-shaft being provided with a depending arm arranged to engage the arm of the sliding block, substantialiy as described.

3. In a ear-coupling, the combination With a car, of a draw-bar provided with a drawhead, and having a forwardly-projecting horizontal arm, arranged parallel with the drawhead, said draw-head being provided at one side With a coupling-pin pocket or receptacle` a coupling-pin mounted on the draw-head. a sliding pin-supportin g block mounted in the draw-head and provided with an arm proj ecting from the draw-head, arock-shaft journaled on the car and provided with a forwardly-projecting arm connected with and adapted to elevate the coupling-pin, and the angular arm depending from `the rock-shaft and located in rear of, and adapted to engage the arm of the sliding block7 substantially as described.

ln testimony that We claim the foregoing as our own We have hereto affixed our signatures in the presence of tivo witnesses.
